# Did you know that the exact speed of light in vacuum is 186282.39705122087012 miles per second?

The speed of light in vacuum is exactly 299792458 meters per second. This is constant as far as we know. Since there is exactly 1609.344 meters in a mile, that means we divide 299792458 by 1609.344 and this yields 186282 and 39937/100584. Since there is 1760 yards in a mile, multiply by 1760, this fraction part will yield to 698 yards, 2 feet, 5 and 21/127 inches exactly. Did you know this? If not, did you roughly know what it was?

Thus the exact speed of light is 186282 miles, 698 yards, 2 feet, 5 and 21/127 inches per second.
